Question about Whirlpool AD50USS Dehumidifier
Compressors have 3 or 5 tubes coming out of the can. Probably 3 in this case. The largest is the suction and the smaller one is the hot gas line. The 3rd is crimped and brazed over. The suction line should be cool or cold (no frost or ice) and the small one should be hot. Be careful of fans. Also, that small line is normally hot enough to burn you. If they are the same temperature, its either low or out of refrigerant (Very common), the liquid line could be plugged (Rare), or the compressor is not pumping (also rare). From here on, you need a compound refrigeration gauge and a line tap. An amp probe would be nice but not needed at this point. If you have an amp probe and the compressor is running and not pumping, the amps will be lower than the name plate RLA or FLA by quite a bit. The name plate should tell you what type of refrigerant it takes. 134A is the new standard but it could be different (R12). Knowing the right type is a must. I have seen compound gauges, line taps, and R134A in hardware stores but you can't add any refrgerant on less your sure no air has gotten in. If the pressure in the suction line matches up close to the ambient temperature when the compressor is off, it has refrigerant. With the gauge on the suction line, start the compressor. If the gauge drops into a vacuum of 25 inches or more, the compressor is probably OK but the refrigerant is gone. If the leak is on the suction side, there will be air in the system. The moisture in the air will freeze immediately at the metering device and it wont get cold. If it all leaked out its another whole process to find and repair the leak, evacuate the system and weigh in the proper charge. I hope this helps. There is a whole process for all of this. Let me know if you have the equipment. I'll get you through.

A dehumidifier is basically an air conditioner, so some coils should feel hot, the others should feel cold.
If no water is collecting, then the unit's compressor is not starting. Typically you have four possible failures causing this: the switch/wiring for the compressor has an open circuit, the motor-start capacitor for the compressor has failed, the compressor itself has failed, or all the refrigerant has leaked out.
If there is evidence that it is 'trying to start', but then clicking repeatedly, this can be a symptom that the refrigerant has leaked out, as some devices have a pressure switch to prevent compressor damage.
Also, a failed start-capacitor can also cause the click-click noise if the device has a current limiter switch on the compressor.
So the short answer is, it's broken :)

Hi, this very well could be the problem. If you have no water collecting and the coils are rusted, yes, I would say this is the problem. The unit has lost its refrigerant due to pin holes in the coil causing the compressor to either go off on a low pressure switch or has locked the compressor up or it is a burn out. It wouldn't be worth the $$$$ to replace the coils and compressor. I am sorry to tell you this kind of news but you pretty much already figured out the problem on your own, I just confirmed it. The only thing that would be any good on the unit would be the blower motor that is running. I hope this has been of help to you.
